HOSE-CLAJIIPING TOOL.

Application filed August 8, 1921. Serial 1\To. 490,581.

To all whom it may concern:

Be it known that T, FRED WILLIS GUNN, .a citizen of the United States of America, residin at Boston, in the county 'of Suffolk and gtate of Massachusetts, have invented new and useful Improvements in Hose- Clamping Tools, of which thefollowing is a specification. 1 This invention relates to tools for applying metallic strips, bands or wires in clamping relation, and 'while having other and more general fields of usefulness is particularly adapted and designed for securing flexible hose to pipes, couplings and the like. A principal object of the invention is to providea tool of this character wherein provision is made for first drawing the metallic band or'wire taut, then bending the same back preferably without requirin any bodily movement of the tool, to make t e coupling ering the band or wire. A further object is to provide a hose clamping tool of compact construction with few parts that are strong and reliable in use, The foregoing and other objects and advantages of the invention will more fully appear from the following detailed description taken in connection with the accompanying drawings, and the distinctive features of novelty will be pointed out in the appended vclaims. Referring to the drawings: Fi 1 is a side elevation of a tool embodyin t e invention;-

.- ig. 2 is a longitudinal section thereof illustrating the operation of clamping a hose; T

Fig. 3 is alongitu'dinal section similar to Figure 2 but showing the operating parts in a difi'erent position;

Fi 4 is a plan view showing the, tool ape pliedg f or clamping a hose and Fig. 5 is a partial longitudinal section I illustrating the clearing of the tool of the wire extremity left therein.

lo indicates the body of the tool which may have its intermedlate portion 10 of a U-shaped cross section with front and rearwardlatera'l cheek portions 10", 10?, this body constituting a housing for the operating members. At the inner end of the body a'pin 11 is fitted transversely therethrough for turning movement, the range whereof is limited by an arm 12 projecting from the pin at one end thereof and engageable with presently further ex lained.

a stop 13 on the body. This pin has a transverse passage 14 therethrough intermediate its length of 'adimension to receive the end portion of the hose clamping band B therethrough. A block 15 is located between the cheek portions 10 and mounted to turn upon the pin 11. This block has a passage 16 through its front'portion adapted in one position of the block to receive the hose clamping band or wire. This block is equipped with a pin 17 adjacent the top thereof which is engaged by a draw-bar 18 extending outwardly through the body of the tool and engaged at its other end with a pin 19 borne at the outer'end of a short arm The arm 20 which is located between the cheek portions 10 is mounted to turn with a stout the outer end of the tool body and equipped at an outer projecting end thereof-with a squared head 22. A pin 23 is fitted for turning movement transversely in the body a small distance outward from thepin 11 and has at one end a squared projecting head 24. This pin hasa transverse passage 25 there through adapted to register with the passages 14, 16 yvhen the parts are turned" to the positions shown in Figure 2, and to then receive the extremity B of the clamping band therethrough. A cutter member 26 is pivoted-in the body at 27 in position so that when it is swung upward as indicated in Figure 5 it engages the periphery of the pin 23 in an approximate tangential relatio n'for the purpose of clearing out the wire extremity as projecting portion of t a circularportion 15 just in advance of the e block15 comprises extending to a point passage 16 where it is cut away as indicated at 15 in a flat, beveled face, the purpose of which is to permit the clamping band to be bent back more abruptly from the clamp loop L by the operation of the tool.

passed through the passages 16, 14, and the pin 23 is set so that said extremity may be passed through the passage 25 thereof. Then upon turning the pin 23 by the application of a wrench or like tool to its head 24 the clamping band or wire is drawn taut under the requisite degree of tension to clamp the nose securely, this resulting in wrapping the band orwire to a greater or less extent around the pin 23 as seen in In use the, head 15 is adjusted so that the band extremity B may be pin 21 which is pivoted at The front embodied in other specific forms without de- Fi ures. Then the pin 21 is turned in aclockwise dlrection as seen in the drawings,

drawing upon the bar 18 and turning the head 15. This results in bending the band extremity sharply around the loop L, i. e. from the positionshown in Figure 2 to that shown'in Figure v3, making enough of a 'a cut off extremity of the wire partly wound around the pin 23 which is readily removed by moving up the cutter 26 as indicated in Figureb andturning the pin 23 further so as to sever-the band. The described means for producing a sharp bend in the clamping band after it has been drawn taut and before severance thereof, .by the oscillation of the head 15 is of particular value and im: portagice in. using the tool in places Where operating space is limited and 'where it would not be 'possible to swing the tool bodily, being thus well adapted for making connections to auto 'obile radiators or the like. I am aware t/liat' the invention may be parting from the spirit or essential attri-- butes thereof, and I therefore desire the .present embodiment to be considered in all respects as illustrative and not restrictive,

reference being had to the appended claimsrather than to the foregoing description to indicate the scope of the invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A hose clamping tool comprising a body theclamping band taut, and means for oscillating said head in the body to bend the.

clamping band for the purpose stated.

2. hose clamping tool comprising a body, a pivot pin at one end of the body, a head mounted upon the pivot pin, said head and pin having passages therethrough to receive a clamping bandor wire, means for oscillating" said head, meant? restraining the oscillation of said pin aftera predetermined movement thereof, whereby to sever the clamping band, and means for preliminarily drawing the clamping band taut through saidpassages. r p 3. A) hose clamping tool comprising a body, a pivot pin at one end of the body, a head mounted upon the pivot pin, said pin and said'head having passages therethrough to receive a clamping band, and said pin mounted for limited turning. movement,
